Publish back-in-stock products with Mechanic.

Mechanic is the one-tool-does-it-all automation app for Shopify. :)

Publish back-in-stock products

Whenever inventory for a product is updated, this task scans all variants and all fulfillment locations, adds up all inventory related to that product, and makes sure the product is published if the total inventory meets your "back in stock" threshold. Optionally, it'll send you an email when it does so.

Runs when an inventory level is updated.
Configuration includes email notification recipient and back in stock inventory quantity.
